Renamed 'Generic Column' -> 'Numeric Column'; Fixed a few resource leaks in processing; misc refinements (#5957)
This PR accumulates many refactorings and small improvements that I did while preparing the next change set of https://github.com/druid-io/druid/projects/2. I finally decided to make them a separate PR to minimize the volume of the main PR.

Some of the changes:
 - Renamed confusing "Generic Column" term to "Numeric Column" (what it actually implies) in many class names.
 - Generified `ComplexMetricExtractor`

Gian Merlino 7e80d1045a Exercise v2 engine in the groupBy aggregator and multi-value dimension tests. (#3698)
This also involved some other test changes:

  engine does merging there.
